Application tiled October 81, 1882. Serial No. 75,547. (No model.)

T0 all whom, t may concern.-

Be it known that I, JOSEPH BREITENMosER, a citizen of the United States,residing at St. Louis, in the county of St. Louis and State of Missouri,have invented certain new and useful Improvements in Cleaning, Hulling,and Grinding Mills; and I do hereby declare the following to be a full,clear, and exact description ofthe invention, such as will enable othersskilled in the art to which it appertains to make and use the same.

The object of my invention is to construct a machine which may be usedfor cleaning, hulling, and crushing or grinding cotton and other seeds,and to embody in one machine the functioi s of several, thus to make onemachine do the work which has hitherto been usually done with separatecleaning and hulling machines and crushing and grinding mills.

In the accompanying drawings, which illustrate my invention, Figure 1 isa longitudinal vertical section of the machine; Figs. 2 and 3, topviews, partly in section,of the set of fingers at the bottom of thehopper; Figs. 4 and 5, sectional side views of the feed-box andfeedroller; Fig. 6, a top view of the stationary cutting and crushingroller and attachments, and Fig. 7 a side View, partly in section, ofthe same roller and its connections in position relatively to theopposite revolving roll.

Like letters designate corresponding parts in all of the figures.

On a suitable frame-work is mounted a feed box or hopper, A. To thebottom of this hopper is secured a small frame, a2, on the top of whichis attached a set of bars or fingers, a3, their ends secured to twometallic strips, a4 c5, as more plainly shown in Figs. 2 and 3. Thesengers are tapering in form, and each nger at its larger end is securedto the under side of the flat plate a* by a screw, c, and the oppositeends of the fingers enter holes in upand crushing rolls. Each fingerbeing se- 5o cured separately to the strips a* a5 by screws and nuts,the distance between each pair of iingers can be increased, if desired,by removing onevor more of the iingers and rearranging the remainingones.

Y B is a feeding-roll consisting of separate disks, provided withsaw-like teeth, mounted on shaft b. These disks may be slipped over theshaft b, separated by rings, and held firmly together by the use of nutson the ends of the 6o shaft b. The teeth a3 extend up between thefingers, as shown in Figs. 1 and 4, and when the roll revolves draw theseed, with its adhering lint or other covering,down to the pair of rollsbelow. 6 5

O and D represent the rolls just mentioned. O is a stationary rollmounted on shaft c. It

is composed of separate-removable disks provided with different sets ofteeth, l, 2, 3, and 4. These different toothed surfaces of the sta- 7otional-y roll C are curved inward to conform to the periphery of therotating roll D, as shown in Figs. 1 and 7. A greater or smaller numbermay be employed. These sets differ in their number of teeth, which arefor the purpose of varying the degreeofneness to which the seeds are tobe broken or ground, as hereinafter described. The shaft c', on whichthis roll is mounted, is supported in the bearings c2 c2, which consistof rods with screw ends passed through the cross-piece c4 back of theframe, and secured thereto by nuts, as shown in Figs. 1 and 6, theopposite ends of said rodsV being turned up to form the bearings for theshaft c', which turns loosely therein. The teeth on both rolls arearranged to move in the grooves formed between the teeth of the oppositeroll. The teeth on the roll D are also formed on disks mounted on shaftd. The disks on both rolls are slid closely together on their respectiveshafts, and held so by screw-nuts on the ends of the shafts. Theadvantage of constructing the teeth on disks is that each can beseparately removed to sharpen the teeth or be replaced by a new disk ifteeth be broken.

E E are arms loosely keyed on the ends of shaft c within the frame, andconnected by rod e', which rod, although shown extending across back ofthe frame, may be placed ,to connect the arms E E at their inner ends,running directly over the roll C. The arms E E run back through slots inthe back of the frame, and are provided at their outer ends with weightse2. Ihe shaft c turns loosely in its bearings on the rods c2 c2 and inthe arms E E, and the object of arms E E, with their weights, is to holdthe face of the roll C normally against the roll D; but when a nail orother hard substance that cannot be crushed falls between the rolls Cand D the increased pressure of the rolls against such substanceovercomes the resistance by which the roll G is held by the weightsagainst roll D, and, forcing the roll C downward and backward, thesubstance falls through between the rolls, and then the weights, actinglike a spring, force the rolls together again. To further admit of thisrocking and sliding motion of the roll C, the rods c2 c2 move to andfro,to aid which movement the said rods pass through smooth rings d,placed in slots e formed in cross-pieces c4.

Vhen it is desired to move one or the other sets of teeth of roll Cagainst the face of roll D, it is done by the use of a key shaped to fiton projection d on the end of shaft c', by which means said shaft isturned the proper distance.

In operating on the seeds,which are introduced into the hopper A afterregulating the fingers a3 to the proper size of the seeds, if it isdesired to simply clean the seeds,the roll C is separated a sufiicientdistance from roll D by moving back the screw-rod bearings c2 to permitthe seeds to pass between the rolls without being crushed. If it isdesired to simply hull the seeds, the roll C is set a little closer toroll D. When it is desired to coarsely crush or grind the seeds ofcotton, corn, barley, wheat, oats, or other seed, the rolls are placedstill closer, andthe degree of iineness to which it is desired to grindthe seeds is attained by the employment of the different grades or setsof teeth on roll C, the teeth increasing in number in each, as hereinshown.

When it desired to grind the seeds very iine or pulverize them, therolls C and D are reversed, so as to present the back of their teeth tothe grooves in the opposite roll, roll C is adjusted near to the roll D,with its greatest number of teeth presented thereto, and roll D is madeto move more slowly than usual.

In practice two machines may be employed, if desired, one adjusted toclean or hull the seeds or grain, and the other adj usted to grind thematerial thus cleaned.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is-

1. In a machine for the purpose herein specified, the hopper, incombination with a set of adjustable tapering ngers arranged across thebottom of this hopper, substantially as and for the purpose hereinspecified.

2. The combination, with the hopper, of the set of tapering ngersarranged across the bottom of the hopper, and adapted to be adjustedboth longitudinally and laterally, substantially as and for the purposeherein specified.

. 3. The combination of the hopper, the set of tapering fingers, and thefeed-roll having disks with saw-like teeth adapted to revolve betweenthe fingers and project above the same, substantially as and for thepurpose herein specified.

4. The combination of the hopper, the set of adjustable taperinglingers, and the feedroll having disks with saw-like teeth adapted torevolve between the ngers and project above the same, substantially asand for the purpose herein specified.

5. The combination of the hopper, the set of tapering fingers adapted tobe adjusted laterally, and the feed-roll composed of disks with saw-liketeeth adapted to be adjusted to revolve between the ngers and projectabove the same, substantially as and for the purpose herein specied.

6. The combination of the stationary adjustable roll having differentsets of teeth, and the revolving roll having teeth which work betweenthe teeth of the stationary roll,l substantially as and for the purposeherein specitied.

7. The combination, with the roll D, of the adjustable roll C, havingsets of teeth differing in number arranged on its periphery, and soplaced as to conform with the periphery of the roll D, substantially asand for the purpose herein specified.

8. The combination of the rolls C D, composed of removable andreversible disks, substantially as and for the purpose herein specified.

9. 'Ihe stationary roll C, composed of a set of removable and reversibledisks or plates, each disk or plate having several sets of teethdiffering in number, in combination with the rotating roll D, composedof a set of removable and reversible toothed disks or plates,substantially as and for the purpose herein specified. j

10. The combination of the stationary roll resting in adjustablebearings, and graduated arms and weights, substantially as and for thepurpose herein specified..A
